Suggestion Name: Exponential ban system for the first 3 bans
Suggestion Description: The length of time a user is banned for should be multiplied by the amount of previous bans they've had, meaning that repeat offenders get banned for longer with every successive time they're banned, discouraging the offenses more than the current threat of a month ban for the 4th time.
Why should it be added?: In the current system, the admin banning the person decides the length of time they'll be banned for, but as long as they've been banned less than 4 times the punishment is minimal, a week at most. The longer they're off the roads for, the less time needs to be wasted punishing them.
When I thought of this, I didn't realise the 4th ban was a for a month no matter what, but I still think it would be useful for the first 3.
